SHABPENING DEVICE.

To all whom it may concern:

Be it known that I, FRANK VAReA, a subject of the King of .Hungary, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sharpening Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to sharpening devices, particularly adapted for the shar ening of scythe blades, and has for its 0E- ject' to provide a device of such class, in a manner as hereinafter set forth for conveniently sharpening the blade at the same time maintaining the sharpening element in position for operation upon the blade.

Further objects of the invention are to provide a sharpening device for blades which is simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel con struction, combination and arrangement of parts, as hereinafter more specifically de' scribed and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views; Figure 1 1s a 'cross sectional view partly in end elevation of a sharpening device in accordance with this invention, and Fig. 2 is a side elevation partly in longitudinal section.

Referring to the drawing in detail, 3 denotes a V-shaped trough supported by legs 4, these latter being secured by hold-fast devices 5, to flanges 6 which project laterally from the sides of the trough 3. Secured to one end of the trough 3 is a vertical bracket 7, which constitutes a support for a seat 8. The trough 3 is adapted to contain water and secured within the trough 3, as well as being spaced from the sides and end thereof, is a V-shaped supporting block 9. Transversely extending bolts 10 carrying nuts 11 are employed for maintaining the block 9 in position.

One side of the trough 3 is provided with Specification of Letters Patent.

a' Vertically disposed supporting arm 12 which gradually decreases in width upwardly and which terminates in a right angularly disposed coupling arm 13, having formed integral therewith a vertically disposed housing 14. Depending from the housing 14 and opposing the arm 12 is a bearing bracket 15.

Formed integral with the arm 12, near the top thereo is a horizontally disposed bearing 15, in which is journaled a shaft 16, having one end provided with a crank 17 and ts other end with a beveled gear 18.

The reference character 18 denotes a gear wheel 19 having extending from each side thereof the hub sections 20 and 21. The gear 19 is supported in the bracket 15 and is permanently in mesh with the gear 18'. The hub sections 20 and 21 have squared openings and extending through said openings is a vertically disposed squared shaft 22, carrying at its lower end, a sharpening tool 23, and having its upper end which projects above the section 21 keyed as at 24, to a cup 25 resting upon the bracket 15.

Arranged within the housing 14, is an in verted cup-shaped member 26, having secured thereto, the lower end of an adjustmg screw 27, the latter engaging with a threaded boss 28, which projects upwardly from thetop of a housin 14. The adjustmg screw is provided with a hand wheel 29.

Interposed between the members 25 and 26 is a a coiled spring 30, the function of which is to maintain the sharpening tool 23 upon the block 9. Carried by the lower portion of the arm 12, is a pair of adjustable guide members 31 for maintaining the blade in position to be operated upon by the sharpening tool 23. Preferably the latter is of inverted cone-shaped.

The crank 17 is utilized for manually o crating the shaft 16, thereby rotating tl fe gear 18 which in turn revolves the gear 19, the latter rotating the shaft 20 and carrying the sharpening member 23 therewith. The block 9 not only constitutes the bearing for the lower end of the sharpening member 23, but also provides a support for the blade. The spaces between the block 9 and the sides and ends of the trough 3 are of such width, thatthe blade can be dipped into the water in the trough when occasion so requires. The distance between the bolts 11 permitting of the dipping of the blade in the water.

The spring 30 acts as a yielding means for maintaining the sharpening member 23 upon the block 9.

What I claim is 1. A sharpening device comprising a trough having arranged therein a supporting member spaced from the sides and ends thereof, an arm projecting upvvaruly from one side of said trough, an operating shaft having a sharpening tool at its lower end, driving means for said shaft, supporting means for said driving means carried by said arm, operating means for said driving means, said operating means supported by the arm, and resilient means for mainta1ning said sharpening tool against said sup porting member.

2. A sharpening device comprising a trough having arranged therein a support- Loenvoa ing member spaced from the sides and ends thereof, an arm pro ecting upwardly from one side of said trough, an operating shaft having a sharpening tool at its lower end, driving means for said shaft, supporting means for said driving means carriedby said arm, operating means for said driving means, said operating means supported by the arm, resilient means for maintaining said sharpening tool against said supporting member, and blade guide members carried by said arm.

ltn testimony whereof I aflix my signature in the presence of tWo Witnesses.
